establishing mesh network by using a nrf52840 devkit and two nrf52840 dongle boards

[Sama]

Hello everyone,

I am going tp establish a mesh network by using a devkit and two or more dongle. take as an example, turning off a led on the dongle boards by using a bottom on the devkit through the mesh network.

Thanks for help in advance.

First this will require merging the usb-cdc example code into the mesh example app you intend to run on the nrf52840 devkit before loading on the dongle.

I have just tried that (usb-cdc + lightswitch_client) on devkit and I get the weird behaviour that the firmware runs ONLY if the segger cable is also plugged into the devkit. IF that cable is not plugged in that the serial port does not appear in device manager.

However, I know the firmware is running as I see it waiting for it to be provisioned.

Frustrating indeed.
Additional frustration is that the usb-cdc example could have been written better so that it exposed a better api for integration.


If anyone has any suggestions as to why the serial port does not appear (yet I know the firmware is working because it is waiting for provisioning) then I will be most grateful.
